We tested the Neon 4 in 1 MP3 Player's playback capabilities with different
types of MP3 files. We tried playing files with different bitrates, constant
and
variable
bitrate encoded files. The device managed to playback
everything we threw at it with no problems, with the exception of files encoded
at 320 Kbps. At that bitrate, the files would playback with a stutter, like
someone is pushing the pause/resume button continuously. Another case where
minor stuttering would appear was while accessing the configuration menu
of the device during music playback.

The Neon 4 in 1 MP3 Player can read ID3 tags as well, and
it can display various information about the songs played, like the song's
title/duration/current position. All this information
is displayed on the device's screen, scrolling from left to right so that
all of the details can be displayed. The device is capable of displaying
correctly
English and Simple Chinese character sets.

As far as music quality is concerned, The Neon 4 in 1 MP3 Player performed very well, but not without glitches. When listening to well-encoded MP3s, the produced sound was good, but at low volume levels or where there were moments of silence during the songs, a very slight hiss could be heard. This effect tended to disappear if we increased the volume from the device.

The Neon 4 in 1 MP3 Player can be used as an FM radio as well. By selecting
the FM radio mode using the player's controls, we can tune in to our favorite
radio station by manually selecting the frequency or by selecting one of the
10 presets. There is a search mode as well in which you can control the 16
presets individually by storing in each one the station you want. The
quality of the reception was good with the earphones
acting as an antenna. What we would
have
liked to see as an option is the ability to disable FM Stereo mode,
in order to improve reception when needed.

Looking at the recording capabilities of the Flash Recorder, the device can
be used as a voice recorder using the built-in microphone. The device records
using the ADPCM codec which produces the well known WAV files. The details
of the recording are as follows: Codec PCM, Sampling Frequency 8KHz, Channels
Mono,
Bits per
sample 8bits. These settings are not adjustable, so the maximum time you could
record with the Neon 4in1 MP3 Player is around 4.5 hours. Each recording is
stored as a file with a .WAV extension in the player, and you can copy it to
your computer and listen to it directly.

The device supports the USB 1.1 standard, and although it offers limited speed
compared to the USB 2.0 standard, the speeds are acceptable considering
the size of the memory. To copy 128MB of data from your PC to the Neon
4 in 1 MP3
Player,
you will need approximately 4 minutes.
